Description

TM
The Thermal Arc Model 200TS is a self contained single-phase DC arc welding power sources with Con-
stant Current (CC) output characteristics. This unit is equipped with a Digital Volt/Amperage Meter, gas con-
trol valve, built in Sloper and Pulser, lift arc starter, and high-frequency arc starter for use with Gas Tungsten
Arc Welding (GTAW), Gas Tungsten Arc Welding-Pulsed (GTAW-P) Gas Tungsten Arc Welding-Sloped
(GTAW-S), and Shielded Metal Arc Welding (SMAW) processes. The power source is totally enclosed in an
impact resistant, flame resistant and non-conductive plastic case.
